How do we scientifically explain the phenomena of shifting perspectives + optical illusions?

The object our eyes detects remains the same, yet our perception of it totally changes (pic related - young vs old woman).

But this isn't done consciously, we don't know what the hell we're doing...how does the brain do it?

Our perception is geared towards recognizing patterns and relations. Optical Illusions are usually not mere shortcomings of our sensory organs, but rather pictures that combine visual cues in a way that our brains is "seduced" to create unwarranted/ incompatible constructs from them.

this one always used to wrangle my jambos. I would stare and stare and never see the old lady. but the thing is the old and young one are drawn in completely different art styles

i see the young lady and she looks reasonably realistic but i don't 'expect' to see an old woman that looks like yubaba from spirited away or something

Thought of it today, evidence has backing in the fact that it's already being used

Here is an example: The famous "checker shadow illusion" is based on us subconsciously considering the influence of shadow on colors. Therefor, we "correct" the perceived color by assuming it is brighter than we see it.

And unless some jerk is playing a prank on us, that is usually justified in everyday experience and therefor not an error.

>we correct

I"m wondering how the brain corrects perspectives

I mean, I just stare at a picture and wait for it to basically solve the puzzle, while I just pick my nose

I dunno wtf is going on, but eventually my brain figures it out

My favorite perspective illusion is the Ames Room:
http://en.wikipedia.org/wiki/Ames_room

Heck, we are so used to rooms being built in a certain way that people can move in that room (read: shrink and grow!) without the illusion being destroyed. I really wish I had first encountered that illusion while being high, it would have so freaked the shit out of me.

Dude, you do not even know what Qualia means. The beautiful thing about optical illusions is that they work for pretty much all humans alike.

>> No.5690504

Your visual cortex uses heuristics to get faster pattern recognition and extrapolation-based results. Optical illusions are failures of those heuristics to correspond to reality, or to converge to a single extrapolated case based on available information and states of mind.

lolnoitsmagic

I'm going to counter argue you

At the basis of our perception is the recognition that all composures are as recompiled conditioned recognitions, the fact that one can not always see the illusion, or occasionally both at the same time, is a failure of the individual to anticipate the bounds of their perception, as opposed to simply lacking it, and redistribute their perception to a non-locallity in their interpretation, IE: The new. The failure is not one of any developed or conditioned evolution in psych, but a failure to interpret themselves easily as something unknown, or as not seeing their interpretation as THE interpretation, as apposed to what is available to develop.
